Title: StripeInvoice was missing properties

I added the additional properties to StripeInvoice as documented here: https://stripe.com/docs/api#invoiceitem_object

These properties include:
AmountDueInCents
DiscountInCents
StartingBalanceInCents

and the one I most cared about:
NextPaymentAttempt

NextPaymentAttempt will be usually be null, with the exception of event notifications where the payment failed (think monthly subscriptions).
